Robust tracking method by MeanShift using Spatiograms

For tracking a non-rigid moving object in a video sequence, it is effective to evaluate the similarity of color histograms. The MeanShift algorithm is one of the popular algorithms. However, MeanShift algorithm may be unable to correspond to extreme changes of the target rotation movement and rapid movement. Recently, Spatiograms which extended the histogram is also studied and the validity is proved. This paper presents a method combined with Spatiograms and MeanShift in order to respond to changes which cannot be tracking by the conventional MeanShift algorithm, and we aimed at robust tracking.
